Abstract: The nucleus 229Ra has been studied via β− decay of 229Fr, the half-life of which was measured to be (50.2 ± 0.4) s. A level scheme with seven excited levels has been constructed. In the Nilsson classification the ground state is assumed to be 5/2+[633↓], levels at 142.8 and 213.0 keV are described as 1/2+[631↓]and 3/2+[631↑],levels at 137.6 and 479.2 keV as 3/2-[761↑]and 1/2-[501↓]. The level structure of 229Ra is similar to the structure in the lighter Ra-isotopes, which have been described as octupole-deformed nuclei.
Description: 14 pages, 3 tables, 6 figures.
